REST Basic Auth with Secure Strings

Demonstrates how to do REST Basic authentication using secure strings.

This example requires Chilkat v9.5.0.71 or greater.

* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* Imagine we've previously saved our encrypted login and password within a JSON config file
* that contains this:

* {
*   "http_login": "mCrOmA7mBA7Au9RuJGb9hw==",
*   "http_password": "jJtiI9TgErTTpqBz9JtHBw=="
* }

loJson = CreateObject('Chilkat.JsonObject')
loJson.LoadFile("qa_data/passwords/http.json")

loCrypt = CreateObject('Chilkat.Crypt2')

* These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
loCrypt.CryptAlgorithm = "aes"
loCrypt.CipherMode = "cbc"
loCrypt.KeyLength = 128
loCrypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
loCrypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
loCrypt.EncodingMode = "base64"

loSsLogin = CreateObject('Chilkat.SecureString')
loSsPassword = CreateObject('Chilkat.SecureString')

* Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
* a randomly generated session key.)
loCrypt.DecryptSecureENC(loJson.StringOf("http_login"),loSsLogin)
loCrypt.DecryptSecureENC(loJson.StringOf("http_password"),loSsPassword)

loRest = CreateObject('Chilkat.Rest')

* Connect to a REST server.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("chilkatsoft.com",lnPort,lnBTls,lnBAutoReconnect)

* Cause the "Authorization: Basic ..." header to be added to HTTP requests
loRest.SetAuthBasicSecure(loSsLogin,loSsPassword)

lcResponseJson = loRest.FullRequestNoBody("GET","/helloWorld.html")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loJson
    RELEASE loCrypt
    RELEASE loSsLogin
    RELEASE loSsPassword
    RELEASE loRest
    CANCEL
ENDIF

* Show the LastRequestHeader that was sent.
? loRest.LastRequestHeader

* The LastRequestHeader looks like this:

* Host: chilkatsoft.com
* Authorization: Basic bXlIdHRwTG9naW46bXlIdHRwUGFzc3dvcmQ=
